XYZ triad axis coordinate system visualiser 2.0

As I study robotics, I often need a axis visualiser, and the usual hand gesture isnt sufficient, I created this model. It can be printed in many different resolution and works without supports.
It is also very useful for 3D designers, teaching/learning situations and a lot of engineering tasks :)
Happy designing :)
2.0 I have made a 50mm version and changed the orientation for faster printing. - Also added a version with my tag.
